I love a flannel
"Very soft and comfortable. I wear a large in REI brand flannels and ordered a large here, but this is just a smidge small through the shoulders, but not uncomfortably so."

“This is a wonderful flannel shirt that’s great for colder days in fall and winter. I got the midnight color and it’s gorgeous, just like the picture. I originally ordered the size small, even though I usually wear an XS because I was scared it would be too small. But actually the XS was perfect, as there was hardly any problem in the chest area or the length. I will say there doesn’t seem to be all that much difference in the S vs the XS, the only difference seemed to be that the small was too long and it had a slightly bigger width. The XS is nice and roomy, and I don’t feel restricted by it. It’s also super warm and soft!”
Never-taking-it-off soft. Our best-selling flannel is back and ready to be outfit-repeated all winter long. Crafted with our signature brushed, heavyweight fabric and sustainable corozo buttons.

"I am so excited to learn about United by Blue and their mission. I bought this flannel in the blue and red. It is soft, breathable, and has a cute, slim fit. 4 stars as I wish it was a teeny bit roomier but otherwise I love it!"
— Julia M. (4/5)
"This is my fourth flannel from United by Blue. I’ve had the others for 3+ years and I love them. They’re soft, they hold up really well, and they are perfect for layered lounging in the house or going out and about. Cannot recommend highly enough"

"I had already a United by Blue flannel shirt. It has aged beautifully, soft and is thicker and better quality than other similar brands, that end up piling and look stretched"

"Love it! Not too heavy, not too thin, just right. Even prettier in rl than in the photos."

"I've been a longtime buyer of the responsible flannel, I own three and they are staples in my closet. I just went to purchase two more in the new colors they are offering this season and I'm quick to return them. The quality and feel is no where near how they used to be, they are so much thinner and not nearly as soft. The fit is absolutely terrible, the shoulders/arms are completely off and uncomfortable. Not to mention the sizing has totally changed, the Large is smaller than the mediums I currently own. Sad to know I will no longer be ordering this style as new colors come out. Plus they charge a return fee, don't waste your time."
